Abstract
Composite materials in various shapes and sizes and in various configurations for use in ballistic armor confined in cylindrical and dome shaped enclosures; held under pressure to increase the impact absorption factor. An armor comprising an auxiliary layer disposed in front thereof at a determined distance wherein said layer comprises pre-stressed members arranged in a spacious pattern. A method is proposed for manufacturing of pre-stressed structure and armor by expanding the cavity into which ceramic materials are inserted so that pressure is applied to the ceramic materials.
